Hi will this engine work on my rc10gt or will I need a new clutch need more power[>:]

Thats the engine I have in mine except I have on woth a pullstart. you can use the stock clutch. for that specific motor you will need to use the non pullstart mount and the non pullstart flywheel if you are planning on using a bump box.

Yes planning on using bump start just did'nt know if my clutch would work.

your clutch will work. but I had to cut about 3/8 inches off the crank.
