Welcome to BBC!

Please see the Announcements at the top of the forum, and add the REQUIRED info to your post. Thanks!

Start by checking the BASICS:

-Visual inspection
-Compression Test
-Spark Test
-Fuel Quality, Delivery, and Pressure/Pressure Leakdown Tests

Better than 90% of all performance problems are found somewhere in the above basic tests.

BTW... is this 23P Trophy a very recent addition?
