f115efi stalling at tick over when in gear

[cobb3333]

Guys it is a 2000 model I had all the fuel internal fuel lines replaced vst filter checked and injectors refurbished recently. My problem is when coming into the jetty at low speed the engine more often stalls . In gear at tick over it is running at 600 revs, is that too low , any way I can increase the tick over revs.
Otherwise engine runs sweet.Anyone had similar problems.Any help would be appreciated.

Can anyone with a 115 tell me what their engine revs are at tick over. I have found a throttle adjusting screw under the intake cover. My engine ticks over at 700 revs , when in gear it reduces to 600 revs. I think it is too low causing the engine to stall , but im just guessing . Any advice would be appreciated.
Thanks
