Status: offline 		OK Guys, here's the latest motor project. This motor is actually a little stronger than my 46. On the stock muffler it's turning a Zinger 18x6-10 at 7500rpm, the MA 20x10 at 6870rpm. With the Abel muffler on it it's turning a Pro Zinger 20x8 at 7560rpm and the MA 20x10 at 7360rpm. One finger, one flip starts! Love those electronic ignitions.

Could you give me some details on your Poulan conversion experience?

I have done a few Ryobi conversions but I have heard these Poulan engines are quite stout!!!!!

Status: offline 		The 42 was from a Poulan Pro 260, I picked it up at Lowes last winter for $89.95. Basically, you have to modify the Hanger Nine mounts a little to fit, make a prop adapter, design and fabricate some kind of mount for the pulse switch (pickup sensor), find TDC and install the magnet in the right place so it fires at 28* BTDC. C-H makes a bolt on conversion kit for this line of engines if you don't have the skills or equipment to make the parts yourself.

Status: offline 		flipflop, I'm surprised your 42cc is running stronger than the 46cc. My 46cc (Pro 295) is not broken in yet, and I was already getting 7000+RPMs with a MA Classic 20x10 on the stock muffler and CH Ign. I'm sure once it breaks in a littler more, and I put on the Abell muffler, it will gain a few hundred RPMs.

I'm liking my Poulan very much and looking to get another to put on my new Sportsman Aviation Super Decathlon. The 46cc might be a little too much power, so I was thinking about either the 42cc (Pro260), 38cc (Pro220), or even the 36cc (Patriot). What's you take on these different ones?

My impression is that these other Poulans don't weigh any less than the 46cc. Is this correct? If that's the case, I'm thinking why don't I just get another 46cc? Your opinion?

Status: offline 		I used the 42 in the saw for 5-6 tanks cutting up a huge oak tree in my frontyard, never ran the 46 in the saw, so the 42 is probably just broken-in a little more. You're right, there isn't going to be hardly any weight difference between the 36 through the 46. I haven't actually compared part numbers, but I think the Patriot though the 42 all use the same crank (never looked at the 46 crank) The 36-42 cylinders appear to be the same with different bores. The 36-42 motors are physically smaller than the 46, about 3 1/8 wide at the mounts compared to 3 7/8 for the 46. My 54 and 60 are both lighter than any of the smaller ones since they don't have to use the hanger nine mounts.

Status: offline 		Thanks. Do you know if the crankshaft taper on the 54 and 60 are the same as, say, the 46? Not having access to a lathe to turn my own prop adapter, I'm stuck with buying what's available from CH Ign. Unless I can get the parts to do a 54 or 60 conversion, I think I'll just get another 46.

BTW, any new project coming up soon? I'm always looking forward to seeing your latest handiwork.

Status: offline 		The 54 and 60 cranks are threaded 3/8s instead of 8mm like the smaller engines. The taper is also slightly larger. You can saw out the center portion of the stock flywheel, turn it the same diameter of your prop adapter. Install the magnet in this.
I'm up to my neck in motors now No new projects planned unless I just stumble across something that looks promising. I do still want a twin though.

Status: offline 		Good tip on cutting the flywheel. I think I will practice it on my Troybilt 25cc first - I've been wanting to put an elec. ign. on it anyway.

Thanks again, flipflop.

Here's a doozie of a question...
I just got a STEAL for a poulan 42cc and a 46cc (less than 120 for both of them). Just waiting for them it to come in.

On the 42, is there a way to make a bracket to hold the stock MAG in place? Maybe build somthing to come off the mounting rails at 90 degrees? Or bolt a flat plate to the front of the case behind the flywheel? ..... Or would it just be best to order the $189 CH conversion kit? Can it be converted to CH cheaper? I.E. just get a 15 dollar prop hub and mount my own magnet.

Thanks!

Status: offline 		I drilled and tapped the holes for the plate to hold my pickup sensor in about the only place possible, there isn't much metal down there. If you do decide to try to fabricate a bracket to hold the mag, keep in mind that you'll have to locate the mag in the same place that its mounted in the saw. If you plan on centering the mag on the cylinder like most engines, you'll have to get a different flywheel or remove the keyway from the stock one and set the timing yourself. Too much trouble for me.
The C-H coversion is the easiest. Do you already have an ignition? Saw out the center section of your flywheel, turn it the same diameter as your prop hub, and mount the magnet in it.
