Thanks cannonball2. I will post some more as my build progresses. I can unfortunately only work over the weekends, as that is the only time I can get free.
Thanks cannonball!! You say that the 'fan' no longer cools the engine. What fan are you refering to? All I removed was the section of the housing that had the recoil starter in it. Could you maybe explain. Sorry, but I am new to these engines.Nice set up. If you want to move the engine fwd some redrill the holes in the mount where it attatches to the clamp and shorten the overhang. Since you have cut the cooling shroud the fan really no longer cools the engine. I would remove the rest of the shroud to allow the air flow to reach the cylinder.
Thanks cannonball. I will have a look at that.The impeller blades on the flywheel forced air up the shroud and across the cylinder then out the back cooling the engine. It has been kown that these engines will cool ok in free flow, but you have it pertty much blocked now.
I was thinking of going with the smaller roller for more torque. I am going to secure the peg again and see if that was the problem with the poor response. If not, then I will go with the smaller diameterMany DIY guys have bolted a BMX foot peg onto the weedwhacker as a friction roller.
The smaller the roller diameter, the more the low end response.
