RE: help!! my engine's busted
The great thing about conversions is that they are cheap. By the time you buy the parts to fix that engine you could get a new one with no ware and tear on it. I would be more concerned buy what caused this one to come apart so it does not happen with your next engine.

RE: help!! my engine's busted
Ernest2,you may want to check your lower connecting rod bearing to see if it is still intact.This happened to me a while back also with one of my 25's when one of the needles in the lower connecting rod bearing decided to abandon ship and make a quick exit up along one of the boost ports and finally ended up getting wedged between the piston and cylinder wall.Yup......not a pretty sight to say the least.Kiss one Homelite 25 "au revoir".

RE: help!! my engine's busted
turbo, maybe thats the case, but i dont know. the connecting rod (if it is- connectin the piston to the shaft- is a bit loose) i dont know if thats normal or not. but maybe thats the reason why the piston hits the wall.
paulfox, that may be the case there in US but here, engines are pretty pricey. but im lucky on this as its on a super low sale
so do you think there's no hope for this one?
thanks!

That small-sh spring in the first photo, do you know what it is from? We had a problem with one of our engines (before anything thinks that I am crazy for using the Royal "We", I mean several of us in our club that do alot of conversions, always great to have a community of nut cases ) when we converted the carb for use, we neglected to remove the ball and spring when we removed the choke butterfly. THis is inset along the choke axle, both the ball and the spring ended up being sucked into the piston and causing much the same damage that you have. This was on a 33cc homelite chainsaw motor. Just a thought.......you should feel priviliged, I only get one thought a day and I am sharing with you

RE: help!! my engine's busted
Not all Homelites are created equal..I bought a new one to actually use in the yard on the weeds..
I filled the tank with 32-1 oil/gas mix and after about 5 minutes the engine quit...Took it apart and found the piston and cylinder destroyed...Some of the chrome plating on the cylinder wall flaked off and trashed it...warranty ? Not likely, Home Depot doesn't if the engine was taken apart, even though it was clearly the fault of Homelite's throw away engine policy....

RE: help!! my engine's busted
I have dismantled a number of Homelite trimmers that have failed. The most common point of failure is the lower rod bearing. When this goes, it usually takes out the piston and cylinder. One of the boat manufacturers offers a superior rod bearing, it would probably behove one to replace the bearing when converting a Homelite. They also offer welded crankshafts. There are better engines for conversion. The newer engines, from MTD, seem to be much better construction.
Ralph;
The Ryobi SS30 I got from the same source had a starting problem that was caused by loose cylinder bolts. So far the plating has held up. My suppliers inform me that no parts will be stocked for any MTD 2 cycle machines as they are not economical to repair.

RE: help!! my engine's busted
ok, i'll let my engine rest in peace[&o]
actually, i checked the bearing, its intact, no loose needles. what probably is the cause? does a propeller not balanced properly caused this? but if so, why did it happen when it was running at low revs and i was just checking my new mounting. hmmmm. did inverting the engine caused this? because i run it at full throttle when it was upright with no problem.
prop nut, i dont think that is a spring, i think its parts of the cylinder wall that had been scraped when the piston chipped.
thankS!!!

The dent in the transfer port looks like it was caused by something tubular. Have you checked the carb to see if something came loose?

RE: help!! my engine's busted
no i havent. but i did remove the ball on the throttle (ones that restrict movement) so did the one on the choke.
maybe something did came into the engine. i'll check it again later.

Of course--this doesn't do you any good right now--as I'm sure this engine exploded on you last summer. Probably too late to return it now.
If you just bought it last week--and can still return it, then do this:
Buy a new one. Take it home and slip the old one in the box. Return it.
I been around the block when it comes to returning faulty items and getting hassled by the retailer.[sm=thumbup.gif]

It was brand new, and yes, running wide open per the instructions that came with it...It would have died anyway, you can't break in a bad plating job on the cylinder..
RC pilet, GREAT idea

Ralph;
I think your owners manual contains a number to call for warranty service. Mine says not to return to place of purchase for warranty.
It also says proof of purchase is required. ie; no receipt, no warranty.

RE: help!! my engine's busted
if there are any spring in there, i didnt remove it. darn!!!
charge it to experience.
do you guys really think theres no hope for this engine? do you think the cylinder is still usable? because i could propbably find a piston here.
thnks!!

You did remove the spring although after the engine was destroyed. It's in the first picture. There's an imprint of it in the cylinder port.
I'm afraid there's nothing about the cylinder-piston - rod assembly that is any good on that engine.
The parts are so expensive and the engines so cheap in the USA, we just throw them away and start over.
It's best that you look for another engine.

It's TRASH. Throw it away. It's not worth messing with. Buy a new one and start over.

RE: help!! my engine's busted
I have to agree with everyone else, start over. If it was me I would head down to Home Depot and pick up a Ryobi CS-30 string trimmer. It has a Homelite 30cc twin ring engine in it. I just got the last one my local store had a week or so ago. They sell for 99.00 around here, well they did all season. Mine was actually the floor display model which was missing the string head and they took 20.00 off the price. And now that you have a fresh start do all the mods, from mild to wild, that are talked about here.

Sure its worth keeping. As a downrigger weight........ok, I am not a fisherman, so I dont know if it would really work for that, but what about a counter balance for a barn door? You could run a rope through the open port and hand other weights to it. Oh, Yeah, and you could use it for catapult amunition for those pesky varmints, and and and, lots of stuff you could use it for. Other than powering your RC airplane with of course [&:]
