RE: CEN GST 7.7
Whats the deal with the stock engine? I am suspicious that it would wear hard because of the displacement. Do people just run high end .28 or .32's then?

RE: CEN GST 7.7
I thought it was just a pain to tune. I kept getting air leaks from the exhaust because the header was a pain to get on. Try to get in contact of a member here called "blackrain". He has a nemsis Converted into a racer and I think he uses a .28 without any problems.

RE: CEN GST 7.7
I have a stupid question. Are there two 7.7 engines from CEN and if so what is the difference? I hear about corsa 7.7 and NX-76 and sometimes NX-77. I just bought a new NX-76 from a nemesis the other day.

RE: CEN GST 7.7
Thanks. I see some people referred to the engine with two different names and wondered. I know they made some changes to them such as the head, carburetor holding pin and the spring/pin to connect the starter shaft to the crank has been removed with a solid pin. I don't like the new setup that permanently connects the starter shaft to the crank.

RE: CEN GST 7.7
I've seen on here where some say the CEN's service sucks but I beg to differ. Long story short, my father purchased a new in the box GST 7.7 back this past spring. We broke the engine exactly as described in the manual but after break in was completed, the engine would overheat and eat a glow plug on every run even when adjusted to factory recomended settings. I wrote CEN and had a response from one of their reps in about one day's time who said to remove the engine and return it to them for inspection. I mailed the engine off to them for my father and in about a week and a half from the date I mailed it out, I had a CEN box in my mailbox. It was a completely new engine! We installed it, broke it in, and have had no more problems. I'll admit the 7.7 engine is a little hard to tune but once we got it right, the thing ran like a "scalded dog!" I'd say their service is great from my experience.

The Engine is what made me sell My GST. It had constant over heating problems. The exhaust heard was a PITA to get out without creating any air leaks.

I would like to see that race myself! Without driving and MGT 8.0, I have driven the GST 7.7, I would guess the GST would win. The MGT seems like it wheelies to easy from the vids I've watched and the GST just takes off like a rocket without wheeling!

I have a MGT! A lot of member give the MGT a lot of crap! From what I read the Savage is the most popular, so it get more respect. I too would like to see the two race! Mater of fact I would like to see the 8.0, 5.9 and 7.7 run just for giggles you know...

RE: CEN GST 7.7
Hey guys...I was wondering if anyone out there has a crank shaft for the 7.7 that they would part with. I've damaged mine and have had to purchase several one way bearings, and I really can't afford $60 for a new one. So if anybody has one for sale or trade please let me know.........thanks............
