    Throttle set up

    Well I have just about had enough with this throttle issue!!! Made a couple silly mistakes due to trial and error. I believe the governor spring is causing problems. It takes a fair amount of force to get the lever to the full speed position, then it won't return to idle on its own. I needed to...

    Air Filter mod.

    Feeling a little skeptical tonight. Lol tough day at work. I've read, and you tubed a bit about stock air filter setups being restrictive. I've always doubted that these clone engines have been engineered to allow just the precise amount of air flow. To suggest that they are on the verge of...

    TC (40) installation issues

    So I got an "off brand" 40 series TC, and a Honda clone "Power Fist" engine. Couple of issues..... On the TC, the driver pulley has a 1" bore with an integral key machined into it. The Key seams to be undersized as there is a lot of play when it is slid onto the engine shaft. I'd say several...

    I watched this video months ago of the Ariel Atom. I kept going back to it, it looked like so much fun! Well I don't have the cash for that kind of machine, but for a fraction of a fraction, I think I can build something that will deliver a thrill.

    Analog or digital tachometers

    I,m thinking of a dashboard, Kill switch, lights, hour meter, and a tachometer. Anybody have any info on tachometer? I've read a few older posts, seams like it is a bit of a problem for single cylinder engines. Lots of "May" or "may not " work comments.

    DIY front Spindled

    So I was hoping to purchase some spindles. Suppliers in Canada Seem to be far and few between. Anything on line was charging more for shipping than the parts were worth. SOOOOO.... I made my own. I think they are serviceable, but a little heavier than bought ones. Now that I have mounting...

    40 series TC installed

    So I got my TC with the red CW spring, mounted on the inboard side as shown in the comet manual. My TC is actually an Ebay knock off, but I think that they are dimensionally the same. I was supplied with the two pulleys and a belt, nothing more. No hardware, no instructions. Referring to the...

    TC 40 series install

    I've started a project from scratch. I purchased a 40 series TC for a 420cc kart. I've watched several videos on TC installation, and every one of them shows the set up like I have in my attached picture. Each video has at least one comment saying it is wrong. "Driven pulley is on backwards."...
