Here's the Dunlap cracker I built.It was purple with black trim.I called it "Ragged Edge" and it had a Sikk 26 cc in it.The drivers were 1:6 scale SWAT team guys who wanted a more dangerous job and signed on as my drivers.If you look between them you'll see a little fire extingusher.

Nice Crackerbox. Where can I pickup a cooling cap for my homelite?

Marine Specialties has them www.marinespecialties-rc.com/engineparts.htm or you could contact Jim Johnson(chipbreakr on most forums) and see if he would make you one,like the one below

.You could also send you cylinder or engine to him to take off the fins and mod it. This email address is being protected from spambots. You need JavaScript enabled to view it.

Good looking motor there. Thanks for the pic and feedback. Do you know Butch T that is on the forums? I know he used to sell Homelite part's. I sent him a e-mail but haven't heard from him.

Butch T is a member on Jims r/c Boat Dock and RC Universe. Should be able to get hold of him somewhere.

Here's a few websites that you might find helpful regarding the homelite.
