A forum for Poulan conversions.

Thanks: I will be watching. Capt,n

Hey Guys,
Heres a couple pics of my 42cc in process of converting.
Using CH "bolt-on" ignition....super easy.

Also made a carb adapter out of cutting board material to rotate for straight shot linkage. We'll see how the adapter holds up.

Enjoy!

Here's a shot of the Front View!

The CH conversion is TOP NOTCH quality. It works with everything from the 33cc to the 46cc.

If all goes well, I will be attaching this motor to the front of my H9 Edge.

Herb: Good looking job you done. Is the 42cc any smoother than the 46cc Poulan? Does anyone know? What size props are best for the 44 and the 46cc engines? Thanks Captinjohn

Thanks Capt,
I think FlipFlop had stated was running same prop 20x8 I think...

I haven't got a chance to get mine running yet...maybe this weekend...maybe next month...5 month old baby boy pretty much runs my life right now....but I get 30 min here and there to "play".

If all goes well, I will replace my RCS 1.40 with this motor on a H9 Edge.

Anyone else wanna post thier conversions?

How about some CLOSE UP shots of CARB MOUNTING on the 46cc motors....I've seen a few... wouldn't mind seeing more though!!!

Your 42 should work well on the Edge. I've got the 36 in mine and it's a great little motor. So far, I like the MA Scimitar 20x8 the best. It will hang on the prop indefinitely and climb out vertically (very slowly) I've got about 20 flights on this prop so far, but still haven't gotten around to taching it. The 20x6 Zinger gives good vertical, but you have to fly around wide open all the time. With the 20x8, normal flying is at less than half throttle and the motor doesn't make near as much noise as with the 18x8 or 18x10. I did install some 4 inch wheels to give a little more prop clearance.

just picked up a couple of old chainsaws to convert. but not sure of engine size #1 is a 2450 2.3 c.i. #2 is mystery ....they are still in the case. can anyone tell how many cc. in the 2.3 c.i. ?

37.7 cc

38cc

Darin

Is this one any good? I thought it was bigger when I picked it up, I was hoping for at least a 42cc. Any thought about the 38cc would be appreciated.

The other engine serial #95199H01736. There is nothing else on the saw anywhere to state model or size.
I also picked up a Homelite 300 which I believe to be a 3.0c.i. Is that correct.

Compared to weed eater motors ANY chainsaw will outperform a weed whacker conversion. Different porting and designed to run all out max rpms, where weedies are governed a bit in different ways.

Your 38cc would be fine on any 1.20 size plane...look for over 1000 sqin of wing area.

Keep in mind the 33-42cc poulans do not have the mag attached to the motor itself. They are attached to the CASE of the SAW. You'll need to get an ignition for them. The 46cc has the mag bolted to the motor but has carb mounting issues (not too much work to make a mounting method). So it's kind of a double edged sword.

Have fun....and go for it...

CrazyHerb and Others,
Can you ID an engine by looking at it? The second Poulan I bought has no model number on it and can not be identified by serial numbers. It is physically larger than the 38cc model but does not have the coil mounted to the engine, so I know it is not the 46cc. Un-like CrazyHerb's engine it has cooling fins on the head, so I'm not sure what it is. See if you can tell which one it is...

Looks like a poulan 2900 model.
Here's the parts breakdown on it...

2.8 ci/46 cc

You have the one model of 46cc that doesn't have the bolt on mag....TYPE 1 or 2 (Older model)

The TYPE 3 models have the mag bolted to the engine.

The CH unit should bolt right to it...and you'll have power almost on par with a $500 motor....

Hope that helps

Twostroker, you got lucky, that's the 60cc with a genuine Gilarooni cylinder on it. Here's a shot of mine.

What do I have. How will it run. Did you make your own carb adapter.
Tim

You have a really good conversion on your hands good luck and keep us posted on it if you do convert it, if not ship to me free of charge of course LOL.oh make sure the piston and cylinder are in good shape first before you comit to converting it.
Darin

I'm not getting the #'s some of you guys are getting on the 46. Topped out at about 6600 on MA 20x8 wood, open exhaust. Was hoping to get at least that on a 22x8. Runs good, good transition and low idle, just need more power. Some other web sites recommend boring the carb, wiil this help? Will a bigger carb help? Maybe the timing is not fully advanced.

if you run a zinger pro or a mejzlic you will se the #s go way up, the regular square tip zinger and MA really bog it down , I get more than that with a prozinger 20x10.

Darin

Yeah, don't know if going to a lighter load prop is what I'm really after. I know it will give me more speed but thrust is what I'm after. I know the MA pulls a lot better than an APC, even at slower rpm.

Crazyherb, how did you hold the crankshaft to tighten the prop adaptor. Are you just getting it as tight as you can and letting locktite hold it?

probably the same answer but i'm feeling helpful so here goes.

turn the crank cw untill the piston just closes the exhaust port, feed through the plug hole as much braided nylon rope as possible and tighten the hub, back off on the crank and rope comes right out. this is the safest and easiest way to lock a piston on any engine when you need to apply alot of torque to the crank.

dave

TKS!

When you do the nylon rope trick, it's best to do so with the crank at close to 90deg to the cylinder bore. You get the max amount of leverage and the least likelihood of damaging your conrod bearings.
