well
i will have to check this out again when i get home.
The parts 150ís piston was a tad smaller then the 150 i am repairing. Didnít really give it much thought to the difference. I just put the newer 150 head and piston on the old case.
Now if the stroke is that much different it will end up with a low competition 150. Now question there is will it be so bad that the 150 will now be a 122. And have no power or will it be close enough.
Now with the information that you all have given me I believe i was sold a 120 parts engine not a 150. Oh well
if it turns out to be a dog then i will order the 150 crank and start over.

I noted that the damaged crank is also bent internally so that would explain the broken crank pin. I donít know if the case is damaged it was just easier to take two and make one.
Like i say i will run this engine and see how it does.
Tonight when i get home i will Measure the old piston and we all will now if i got a 120 or a 150.
Dam Ebay buy ten things and get one bad. Lol

What ever method you find easiest, the check is even easier. Bring the crank to TDC on the exhaust stroke and look for a very symetrical action on the intake and exhaust rockers as you rock back and forth from TDC.

Like I said before, I have a 150 crank with a very small runout on the shaft, outside of the bearing area. Real easy to straighten. Yours if it help.When you say "smaller" do you mean in diameter????
There are no Saito pistons I know of that are within less than about 2mm of the 150 piston diameter. The 120 will be 2 mm smaller, the 180, 2mm larger. Not much fudge room there! The stroke should be the same on any 150 AFAIK.

hey Dave, thank you for the link, I looked at a few of their chargers on line but have not seen them all, I didn't know they made so many, but after seeing the ones in your link I just may buy a Battery Tender !!

but you know I am old school, I like to be involved in things, I like the switches and gauges of the older days, and that's what I am lured to. I dislike the switches/gauges on the Battery Tenders, but still I may buy one !! because I know in the long run down the road that will be the better thing to do, they are very good chargers, my brother told me once, that I do not like change,, I guess so.

it's a bit more money but this one will do just what I want !!!!! I will be able to brag about how well it works, not how big it is LOL hee hee hee

Pete, I like AC/DC too, they are great, it;s too bad about the broth !! a lot of energy there.. but go to YouTube and check out "Papa Chubby" the guy is like Angus, like Angus but on American Southern Rock,,, Papa Chubby , man

I had a 1999 dually and want to get another one, this one showed up in your neck of the woods, but has too much rust. I did find one in Milwaukee though that I just might pull the trigger on. I need to call the credit union first to see if they will do a small loan on part of it. I want to keep some cash in reserve in case I need to put tires or other parts on it. The one I found is only RWD though, and would prefer 4WD, but what I find in similar condition and miles are slightly newer and twice the price or more.

I actually got away with using this guy in Gloss Black, the cylinder wasn't skinned up
too badly. The crank case is going to require the rattle can miracle.

Doubtful the 150 jug will run correctly, if at all on a 120 crank Crunchy. You would not only be loosing displacement (cc), and overall compression (ratio), you would also be widening the quench zone at the top of the stroke. You need a tight quench zone to ensure proper flame propagation. Wouldn't hurt anything to try it though.

Well itís definitely a 120
i will still run it and see what happens.
Should be uneventful. So now i need to order a crank
sorry I really donít want to mess with a slightly bent one, if it was for me I wouldnít care but for someone else needs to be good.

What?
That little sin hider doesn't have a rattle.?


Oh well, you could dip it in a bucket of paint and hang it on a clothesline and the result is about the same

Here is another painted Saito that needs "touch up" frome a rattle can... Only $1200 on eBay right now!

Call me a tight ass but how does one justify the cost of that engine? Just because it fits in a car

And you still have to paint the top half.

Or better still, strip the bottom

Looks to me like someone at Saito couldn't make up his mind. Perhaps a Bi-Polar designer.

I still canít believe they make something for a car and itís three times the price of a airplane engine.
What do they do different. What does a car engine have the an airplane engine doesnít?
With that said I still like the price of the airplane engine they can keep there car engines
