Hi to all
I´m experiencing some situations and I decided to ask some help.
I´m still breaking in my engine (Grubee 58 cc Gen-IIa). It probably has 15 km (10 miles) on it. I´ve changed (since first start) the stock air filter by a hi flow from SBP.
First issue: Don´t need to pull the choke when starting. In fact, when I pull it on, it gets very hard to start. The only time that I used a little of the choke was on a cold night. Is it normal or something in carb tuning could be wrong?
Second: After starting the engine, i´ve noticed that I can´t throttle the bike more than 20%, because if I do, it starts "failing" and looses power, especially in uphills. In fact, in this situation, I have to reduce a little the throttle and the bike stabilizes, and slowly and gradualy it gains some speed. When the engine warms up, the problem decreases on straights but keeps happening on uphills. Pulling the choke increases the problem.
So the problem is from mid to full throttle.
I disconected throttle cable and I changed the "c" clip to the intermediary position (3rd position, middle position). Innitialy, it was set on the 2nd position (one step leaner). I Made that change because of the failed choke test on uphills, but didn´t notice any acceptable result.
To finish, I didn´t make the spark plug test because kill switch isn´t connected, because of the problems other users posted in starting.
Any help?
