RE: Vibration Help

Hi all,

One issue I ran into with a 35cc homelite chainsaw convert was had very bad vibes when using a heavy prop (master airscrew). A switch to a wood prop really smartened it up. Both props...

RE: Surplus McCulloch's

I built the hub for this engine. As far as I can remember it was fairly straight foreward.( it was a while ago) I remember having to re-thread and cut off some of the long extension. I think Carr...

RE: How much can I trim off Homie 25 fins??

Hello all,

I don't know about the homies but I run a Mac -28cc with trimmed fins without issues. The engine is not cowled.

I don't think there is much weight saving but I think it looks...

RE: Surplus McCulloch's

Hi All,

I have converted a few of these 28's and they seem to run very nicely. They are not powerhouses and are on the heavy side but they are stone cold reliable. I have included pics of my...

I was very interested to read all the discussion on the .07 and a lot of it confirms my experiences with this little engine. I had a plane (own design) which had a Norvel .061 in it and the thing...

Finished product

Here is a pic of the finished manifold. I still have to port the base to match the flange on the cylinder. I gained over 1/2" clearance and put the carb back to where it has about another 1/2" of...

Walboro Wyl/wyj

Thanks for the info! As I understand from the walbro site the needle adjustment in the middle of the barrel is for the idle mixture and the high speed is set by the main jet. In my estimation this...

Has any body out there had any experience using the WYL/WYJ series of rotary throttle walboro carbs on a R/C conversion. I realize that the high speed jet is fixed and might take some playing with...

Turn that Carb

Great minds think alike capt'n. I've already started on the "plumbing". The link to the toni clarke website shows this very same mod. The elbow is the exact I.D. of the carb plate so the size is...

Turn that Carb

Captain,

My conversions

I currently have one very successful "saw" conversion in the form of a 36cc homelite. This was an old XL-1 saw and was a fairly straightforward conversion. These saws are a dime a dozen at any small...
