RE: For all you homelite fans!!!

RE: For all you homelite fans!!!

It's not your prop, I've been building homies for a long time , you raise that strut and set your pipe around 12" and it will sling that 482 or the 280 with ease . You should be in the 40's at least .

RE: For all you homelite fans!!!

Raise it as far as you can , run it and if it improves , then make it surface drive , you will see a big difference . From the center of your pipe [ largest Dia.] to the face of your exhaust port ....

RE: For all you homelite fans!!!

RE: For all you homelite fans!!!

The engine is a 2 port  and I set the timing at 176 degrees on the exhaust ,so it should still have some torque.

RE: For all you homelite fans!!!

I have bumped it up over 15500 rpm on the test bench and it is smooth as can be . All this is experimental , you won't know what it will do until it in a boat .

RE: Homelite

25cc - 1.312
30cc - 1.437
If it's a stock homelite 25cc , it will have a bridge in the exhaust port . If it's been modded the bridge might have been removed .

RE: Another Homelite 30cc

After you stuff the crankcase , you can take a grinder and unshroud the rear transfer . I do it to all my engines . Does make a difference.

RE: Ryobi/Homelite 30cc duration numbers???

Why would you need to fill the intake port. The #'s are usually low and the port needs opened up . But yes it would work on the intake side. I did a 4 port homelite before, I ground the transfers...

RE: new boat have some ?

The John Deere 30cc is a homelite built engine. You can take the pullstart housing off your older engine and it will fit on the Deere , if you want to have the engine mounted in the same place.
