Ten stiches man that had to hurt. Did you hold your finger in pain and amazement and sheepishly look around to see if anyone saw you do it lol? Isnt it funny thats the first though in your head is man i hope nobody saw that.
Anyhow thats not a bad idea on the test prop. I am wondering how accurate the adjustment factor is gona be though.
for the timing wheel that i made, i just did a google image search. It took a few mins, but i found a suitable one kinda like yours. I just printed it off and used spray adhesive to glue it to an old beer box.
Its starting to get warm here again, and im going to build an actuall test stand then i will try and get some rpm numbers.
Hey combat, if u figure that u have too many (if thats possible) of those poulan engines, how much do you want for one? I have been looking around here for one, with no luck.
I think your gona want something more rigid for your degree wheel. I used 1/4" plywood. I think 6 inches is about right. That gives good resolution and allows you to mount your needle off of the ignition coil boss
As far as a poulan engine I will give it to ya if you pay shipping. Let me take a pic and send it to ya so I can be sure we are talking the engine you want. Im sure I will get more in the future as they seem to be the most common engine. In a way its hard to belive you cant find one when i found so many lol. Heck if ya want a couple of them thats fine to.
I finally scored a cheap set of inline roller skates to rob the wheels off of for my test stand. I will give construction details of this as i get back to work on it. I may be monday though as today I had to work on the airfield mower to get it ready for the upcoming season and tommorow I have to go help with feild maintenance.
Oh yea also on the engine pile i found all the ryobis but one had what I consider to be the good high compression heads and none have the slits I keep hearing about. I still yet have to find one witht the slit. Only one engine has the two runner per side transfer port and low compression head. There is one cylinder in particular while even having the single ring piston it has great compression and is not scared in any way. I cant wait to try this one as my original cylinder had some minor scoring to it.
