Here are a few tips on running your Comer W60
The following amendment needs to be made to Page 6 of the Kart Race Year Book, A1.4, replacing the sentence beginning engine lubricant: Engine lubricant must be a synthetic oil meeting the requirements of the JASO FC standard to ensure that the engine exhaust emissions meet the standards set down by the MSA. 'JASO FC' is to be clearly marked on the lubricant container and is available from the majority of oil product manufacturers.
Set jets by turning in until lightly seated closed, then turn out the low jet 360o and the high jet to 260o. This setting will give reliable performance, use of a washer soldered on the high jet (must not measure more than 12mm OD) is recommended to enable the driver to control the mixture to give optimum performance. However in testing we found if the carb was leaned in less than 260o on the high jet the performance fell off. Therefore the carb required little or no adjustment as the engine runs at a consistent temperature giving consistent lap times. Warning! Use of the washer on the high jet is recommended for experienced drivers only as adjusting the mixture incorrectly can cause seizure. Always pre filter fuel mix through a coffee or paint filter before filling up your tank.
Always keep a log of running times for each of your engines as this is very important information not only for yourself but also for your engine builder.
